A sinus of Valsalva aneurysm is a rare cardiac anomaly, and it is usually clinically silent. However, it may lead to symptoms when it compresses adjacent cardiac structures. Herein, we would like to report a 45-year-old lady with exertional dyspnea who was first diagnosed with having a cystic cardiac mass on transthoracic echocardiogram. Then, transesophageal echocardiogram and cardiac computed tomography revealed an unruptured aneurysm of noncoronary sinus of Valsalva.
Keywords: aneurysm; aortic reconstruction; cardiac mass; noncoronary; right atrium; sinus of Valsalva.
